Irisviel von Einzbern (アイリスフィール・フォン・アインツベルン, Airisufīru fon Aintsuberun) is a homunculus. She is the wife of Kiritsugu Emiya and the mother of Illyasviel von Einzbern. For the Fourth War, Jubstacheit von Einzbern decided to create a humanoid shape as the Grail vessel that has a consciousness and can be independent to defend itself from harm. He used the archetype base of Justeaze Lizrich von Einzbern to create Irisviel, thus referred to as a Justeaze-late model. The one who became the mother body of the ultimate homunculus among all Einzbern homunculi in the past, she is the only one who experienced motherhood and gave birth to a successor. Kiritsugu Emiya first met Irisviel when she was created inside a tube. Through his interactions with her, he found her to be useless and Kiritsugu expressed his frustration to Jubstacheit regarding Irisviel's lack of understanding towards protecting herself and interacting in society. In response, Jubstacheit decided to prove Irisviel's durability by casting her into the wastes of the Einzbern forests. Disgusted with Jubstacheit's actions, Kiritsugu rescued her and personally began educating Irisviel about the current society and the modern world so that she could develop a sense of self. Her rapid development and unexpected insights toward mankind surprised Kiritsugu and they gradually fell in love with one another. However, Kiritsugu knew that their love would end in tragedy as he would have to sacrifice her for his ideals. For his sake, Irisviel wanted to conceive a child for him so that he would have a new hope after the war. Because the plan of conceiving Illyasviel was decided after Irisviel was coined, her pregnancy of Illyasviel was not much of a natural development since it was an additional role imposed onto her that she originally was not supposed to have. An exception among Einzbern homunculi whose functions are determined when they are designed. It was due to Jubstacheit's judgement that it would be more efficient to nurse a child rather than produce a homunculus.
